The expression 3x^2 + 18x - 76 has to be divided by x - 8.

(x - 8) | 3x^2 + 18x - 76 | 3x + 42

............3x^2 - 24x

---------------------------------------

.......................42x - 76

.......................42x - 336

----------------------------------------

..............................260

When 3x^2 + 18x - 76 is divided by x - 8, the quotient is 3x + 42 and the remainder is 260.
